sucrron CLEANER.

Application fled August 4, 1821. Serial No. 489,680.

To all whom it may concern:

Be it known that I, WILLIAM V. ORB, a citizen of the United States,residing at Cleveland, in the county of Guyahoga and State of Ohio, haveinvented a certain new and useful Improvement in Suction Cleaners, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings.

This invention relates to suction cleaners and has for its objects theprovision of a device of this character which shall have a minimumheight so as to be insertable below furniture, together with a maximumof stability to resist overturning; which shall be constructed with aminimum num- 'ber of parts, with a maximum of .simplicity in casting andwith a minimum of machine work; "the provision of an arrangement ofparts which shall cooperate with unusual effectiveness for the removalof dust and litter; the provision of a device having improved facilitiesfor the attachment of an extension hose; the provision of a suctioncleaner possessing a totally new arrangement of motor, fan, and nozzle;while further objects of the invention will become ap arent as thedescription proceeds.

n the drawings accompanying and forming a part of this application Fig.1 represents a side elevation and Fig. 2 a front elevation of myimproved cleaner; Fig. 3 is a horizontal sectional view taken upon theline 3-3 of Fig. 2; Fig. i is a top plan view of the cleaner; Fig. 5 isa bottom plan view with a part of the bottom plate broken away; Fig. 6is a rear elevation drawn to a reduced scale; Fig. 7 is a cross sectioncorresponding to the line 77 of Figs. 1, 3, 4 and 5; and Fig. 8 is adetail view illustrating the mode of attaching an extension hose.

Describing the parts by reference charactors, 1 represents the fanchamber which is preferably made of castaluminum with its axishorizontal and having at its forward side a circular opening 2 adaptedfor the reception of the motor base 3, and having its rearward wall 4formed with a central inlet opening 5. Communicating with this inletopening are two converging passage-ways 6 which extend past the twolower quarters of the fan casing and thence forwardly to the extreme endof the cleaner nozzle, said pas e-ways owing wider toward the forwar enduntil they meet at the inlet mouth 7. The rearward part of eachpassage-way is formed in a thickened boss 8 integral with thefan-chamber casmg, these bosses being provided at their junction with aremovable cover 9 for which can be substituted an extension hoseconnection 10, applied immediately to the inlet opening 5 so as toautomatically cut off the flow from the passage-ways 6, as shown in Fig.8. Immediately below this opening the two branches are spaced apart toprovide a notch 11 for the accommodation of the caster 12 which ispivoted to a bracket 13 cast upon the bosses at this point. Forward ofthe fan chamber casing the passageways 6--6 are preferably formed asopen bottomed channels, the tops 14 and sides 15 ofsuch channels beingintegral with the fan casing, but the bottom thereof being formed by a.removable plate 16 of appropriate shape detachably secured thereto, itsforward end constituting the rear lip 17 of the inlet mouth 7. The roof18 and forward lip 19 of this inlet mouth are integral with the fanchamber casing, provision being made for a suitable brush, if desired,such as that shown at 20. Journaled across the top of the nozzle isarock.-

shaft 21 having cranked end-portions 22.

22 on which are journaled the carrying wheels 2323 which support theforward end of the cleaner. Projecting tangentially and also rearwardlyfrom the fan casing 1 is the outlet neck 24 adapted for the reception ofthe dust bag 25. This brings the inlet and the outlet openings of thefan chamber on the same side thereof with each other and on the sideopposite the motor and nozzle. It will be understood that it is equallywithin my invention to make the channels by casting about cores in theusual manner.

The base 3 which carries the motor is rigidly secured across the opening2 by means of suitable screws 26-26, and is formed with studs 27 towhichis attached the frame of the electric motor indicated generally at 28.The shaft of this motor is approximately parallel to the plane definedby the wheels 13 and 23 and perpendicular to the direction of the inletmouth and coincides with the axis of the fan chamber into which itprojects, being there provided with a suitable fan 30. Detachablysecured to the front of the fan chamber and the top of the air channelsis a. housing 31 which,

within the scope of this invention, may assume any desired form, butpreferably slopes forwardly and simultaneously flares laterally so as topossess an attractive appearance. This cover may be provided withopenings 32 for ventilating the motor, or may be left imperforate ifdesired; and the bottom plate 16 may also be provided with perforationsshown at 33 in Fig. 5. In order to secure the handle 35 tonthe cleanercasing I have shown the two topmost studs 27 as formed at equal heightsone at each side of the motor, and threaded for the reception of thetrunnions 36-36 which project at opposite sides of the cover 31 and havethe handle forks 37 detachably sprung thereon.

Any suitable means can be employed to secure the rock-shaft 21 inadjusted position, the preferred means consisting of an arm 40 pivotedtransversely of the shaft and projecting through a slot 41 formedtherein, one side of said slot being formed with notches 42 to receivethis arm and the arm itself being provided with a spring 43 which tendsto force it into these notches.

When constructed as shown herein the coring and casting are very simple;only one aluminum casting is required; the bottom plate 16 and top cover31 can be formed of-stampings; and the only machine operation necessaryis the train up of the a erture 2 for the reception 0 the motor ase 3and the boring and tapping of the holes for the attachment of theassemblin screws. The air passage-ways 6--6 are so eepened "vertically,combined with their gradually decreasing width rearwardly asto possesssubstantially the same cross-sectional area at all points, so that theair passing therethrough may exhibit no eddies or pockets. As a resultall dust and litter carried into the suction mouth acquires a very greatvelocity while movin along the substantially horizontal part of t epassage-way with the result that comparatively heavy articles areelevated into the fan chamber without difficulty. By virtue of thelowdust fan eflect there is practically no direct lifting of the litter atthe inlet mouth but the air blowing across the top of the carpetfrom theforward lip 19 (which is preferably elevated slightly above .the rearlip for this purpose) sweeps the'litter up a; gradual in-, cline onlyuntil the same arrives at apoint where the air stream is so deep andstrong that it is elevated without difficulty. Furs thermore by makingthe motor and motor top thereof in the usual way if desired; also that acast metal top can be used instead of a stamping: that the handle can besecured at other points and in other modes; that I do not restrictmyself to a construction wherein the nozzle is integral with the fanchamber or wherein the top plate is sep arate from the nozzle: and ingeneral that many changes in detail and arrangement of parts can be madewithout departing from the scope of my inventive idea as defined in theannexed claims.

Having thus described my invention, what I claim is:
